Description

Notes

Built-in common functions operate component-wise and the description is
per-component and are implemented using the round to nearest even rounding mode.
We use the generic type name gentype to indicate that the function can
take float, float2, float3, float4,
float8, or float16 as the type for the arguments.

The built-in common functions are implemented using the round to nearest even rounding mode.

If extended with cl_khr_fp64,
generic type name gentype may indicate double and
double{2|3|4|8|16} as arguments and return values. If extended with
cl_khr_fp16, generic type name
gentype may indicate half and half{2|3|4|8|16} as
arguments and return values.
